Hammerite Metal Paint works with the Hammerite Metalmaster Electrostatic Paint Gun. Its 3D Wrap precision technology means that the paint coats itself around curved surfaces such as railings so that both sides are painted at the same time with low overspray. It makes painting ferrous metal quick and easy with long lasting professional results. * Using 3D WRAP precision technology the paint has an electrostatic charge that, when applied by the paint gun, paints both sides of the metal at once. * Enables the task to be completed 4X faster than brush. * Unlike conventional gloss paints, Hammerite does not require the use of a primer or undercoat and provides a high quality, professional finish in Smooth or Hammered.
